I have used the nerivio for about 10 times now and even with my migraines that are 30 out of 10 and me in bed for days and crying and wanting to cut my head of or just wishing that I just wouldn't wake up it has it to bring them down sometimes down to a 12/15 which for me is saying something because when mine are that bad I'm usually being admitted to the hospital different IV drugs for at least 5/6 days. I have even been in there for as long as 2 weeks getting keditmine treatments. So this has help. It doesn't make it go away but it does help with my other meds. Glad I found it.
